Question

Бассейн, объем которого 240м кубических, одной трубой наполняется за3 часа, а второй трубой-за 4 часа. На сколько больше воды поступает в бассейн за 1 час через первую трубу, чем через вторую?

Answer 1

240/3=80м^3 - в час наполняет первая труба
240/4=60м^3 - в час вторая труба
80-60=20м^3 
Ответ: на 20м^3

Answer 2

Calculating Water Inflow Rates for Two Pipes

To calculate the difference in water inflow rates for the two pipes, we can use the formula:

Inflow Rate = Volume / Time

Given: - Volume of the pool = 240 cubic meters - Time taken to fill the pool with the first pipe = 3 hours - Time taken to fill the pool with the second pipe = 4 hours

We can calculate the inflow rates for each pipe using the given information.

Inflow Rate Calculation

First Pipe: Inflow Rate for the first pipe = Volume / Time Inflow Rate for the first pipe = 240 / 3 Inflow Rate for the first pipe = 80 cubic meters per hour

Second Pipe: Inflow Rate for the second pipe = Volume / Time Inflow Rate for the second pipe = 240 / 4 Inflow Rate for the second pipe = 60 cubic meters per hour

Difference in Water Inflow Rates

The difference in water inflow rates between the two pipes can be calculated by subtracting the inflow rate of the second pipe from the inflow rate of the first pipe.

Difference = Inflow Rate of First Pipe - Inflow Rate of Second Pipe Difference = 80 - 60 Difference = 20 cubic meters per hour

Therefore, the first pipe allows 20 cubic meters more water to enter the pool per hour compared to the second pipe.
